(VEN) - Promulgating a national action plan on air pollution control and reducing particulate pollution are just a couple of priority solutions proposed by the Ministry of Natural Resources and Environment to control and reduce air pollution.
According to experts, air pollution causes are perse, of which air pollution in cities caused by traffic accounts for about 70 percent, and the rest derives from industrial production, construction and people’s daily lives, agricultural and craft village activities, trans-border pollution and greenhouse gas emissions.
Data from the Center for Environmental Monitoring regarding the actual condition of the air in the 2008-2012 period show that the dust content continuously remained at high levels, especially along traffic axes and highways where the traffic density is high. In residential areas of big cities, air pollution was much higher than the allowed limit in Vietnam.
Air pollution has a very big impact on human health, especially the respiratory tract. Research results show that polluted air leads to a decline in human health, accelerate the human body’s aging process and facilitate the spread of communicable diseases.
The results of surveys carried out by the Vietnam Environment Administration in Phu Tho and Nam Dinh provinces showed that their annual per-capita expenditure on efforts to overcome the damages caused by air pollution on human health was an estimated VND295,000.
In fact, air pollution has become a problem that concerns the whole society. Relevant authorities have issued many documents and technical standards highlighting the necessity of improving the environment and the air in particular. However, specific legal regulations in this field are still lacking; the functions as well as the responsibilities of environmental officials remain unclear and overlapped; air standards have yet to meet practical demands. Due to these reasons, the control of waste has been ineffective, having a big impact on socioeconomic development.
In the opinion of experts, the state and relevant authorities must promote further efforts to ensure effective air quality management and control. However, air pollution is a complicated problem that is related to activities in different fields. Therefore, efforts to control and minimize air pollution must be based on synchronous measures such as improving mechanisms, policies and laws, especially specific legal documents on air control. It is necessary to apply strict sanctions to those who violate air protection regulations and stipulate clear criteria based on which air pollution can be assessed. Air monitoring stations with modern equipment must be built. Particulate pollution causes must be put under effective control and restricted by intensifying the supervision over construction and transport activities, applying cleaner production methods, increasing the green space in urban areas and boosting communication to improve the community’s awareness of air pollution. /.
